Abstract. It is well-known that the remaining term of any 𝑛-point interpolatory quadrature rule such as Gauss-Legendre quadrature formula depends on at least an 𝑛-order derivative of the integrand ...

For Gaussian quadrature rules over a finite interval, applied to analytic or meromorphic functions, we develop error bounds from contour integral representations of ...

Quadrature rules are mathematical techniques used to approximate the definite integral of a function. They are essential in numerical analysis and scientific computing, particularly when dealing with ...
